what is the 12 digit service number of the module?

Which t-harness are you using?

If you are not using a t-harness, check your DATA wire and make sure that it's on the middle pin of the immobilizer connector. There are 2 green wires in that connector that can easily be mixed up.

 

Also, use the latest 70.38 firmware.
